Scorpion Ultraviolet UV Light
Some may already know that scorpions glow under ultraviolet light, but have you ever wondered why? Well, there is still no definitive answer, but scientists do know that right after a scorpion sheds its shell, it doesn’t glow until the new cuticle hardens. This could possibly mean that the substance that causes fluorescence is a byproduct of the hardening process itself, or something that the it secretes not long after molting.

NASA Mars 2020 Perseverance Rover Rock Sample
NASA’s Perseverance Mars rover is making final preparations to collect its first-ever Martian rock sample, which will be transported back to Earth on future planned missions. It’s currently searching for a scientifically interesting target in a part of Jezero Crater called the “Cratered Floor Fractured Rough,” and the mission is expected to begin within the next two weeks.

Neutron Star Mountain Gravity Astronomy
Scientists have discovered that the mountains on neutron stars stand just millimeters tall. These stars are some of the densest objects in the universe, weighing as much as the Sun while only being around 6.2-miles (10-kilometers) wide. These are formed when a massive star runs out of fuel and collapses, with every proton and electron in the object forming a neutron, or a a neutrally charged subatomic particle.

Crush Lava Hydraulic Press
In nature, nearly all lava of the Earth’s crust consists of silicate minerals, like pyroxenes, amphiboles, micas and quartz, while rare nonsilicate lavas can also form by local melting of non-silicate mineral deposits. However, lava can also be made in the lab in the form of molten copper and aluminum, but this substance is slightly thinner than the material spewed from active volcanoes.

Shanghai Astronomy Museum World's Largest Planetarium
Spanning 58,600-square-meters, the Shanghai Astronomy Museum boasts the world’s largest planetarium and it just opened to the public today. The museum itself showcases innovative architecture, compete with themed exhibition areas, immersive technologies, and scientific collections. When viewed from the air, the main building resembles a collection of astronomical instruments with a circular skylight, an inverted spherical dome, and a dome theater.

The previous internet speed record of previous record of 178Tbps set a year ago has just been obliterated by a team of researchers at Japan’s National Institute of Information and Communications Technology (NICT). They managed to transfer data at an astonishing 319Tbps by using advanced fiber optic technology with a 4-core optical fiber of 0.125 mm standard outer diameter.

You’ve probably seen videos of sound shattering glass, and the world famous Slow Mo Guys wanted to take the experiment to the next level. So, they used a Phantom TMX 7510 high-speed camera capable of shooting at 187,500 frames per second to capture a wine glass shattering using nothing but sound, around 7500x slower than you can see with your own eyes. For those wondering, the camera alone costs upwards of $60,000+ USD. Read more for the video and additional information.

Chef Mario David García Mansilla decided to showcase his pizza making skills in one of the most unusual ways ever. Since he grew up close to Pacaya, one of Guatemala’s most active volcanoes, it’s now used as a giant pizza oven for his Pizza Pacaya business. These days, you can find him cooking up a hot pie for hikers visiting the active volcano, which does command a premium due to the difficulties and dangers of such a stunt.

UCSF Facebook Brain-Computer Interface Paralysis Text Sentences
Researchers at The University of California, San Francisco (UCSF) and Facebook developed a “speech neuroprosthesis”, or brain-computer interface, that allowed a man with severe paralysis to communicate in sentences. How so? This interface translated the signals from his brain to the vocal tract directly into words that appear as text on a screen. This also marked the first time in over 16 years that he’d been able to communicate without having to use a head-mounted device. Read more for a video and additional information.

UC San Diego Fingertip-Powered Wearable
University of California San Diego engineers have developed a thin, flexible strip that can be worn on a fingertip and used to generate small amounts of electricity when a person’s finger sweats or presses on it. It can even generate power when the person is asleep or sitting still, which means this wearable can harness the energy extracted from human sweat even when a person is not moving.
